To L7/Z whom it may concern,.-

l yBe it known that 1, JOHN C. BROOKS, a citizen of the United States, residing at Paterson, county of Passaic, State of New Jersey, have invented an Improvement in vLoom- Shuttles, of which the following description, in connection with the accompanying drawings, is a specification, like figures on the drawings representing like parts.

This invention relates to loom-shuttles. and has for its object to provide a shuttle with a novel controller for actuating loomstopping mechanism'or some other loom-controlling mechanism, which controller is normally heldin inoperative position, but is adapted to be thrown into operative position Wh en certain conditions arise that will make the weaving defective-such, for instance, as the exhaustion, or substantial exhaustion, of tlfe weft in the shuttle or the occurrence of a i lo at in the warps, &c.

The controller is in the form' of a member 'which is pivoted to the shuttle, and 'it isheld in its linoperative position by a retainer which is positivelyloeked against movement, and the lock for the retainer is so arranged that whenever the abnormal conditions arise-eas, for instance, whenever the weft Iis exhausted or a ioat occurs--the lock will be actuated to release the retainer and the latter will'be moved to release the controller, thereby permitting said controller to .be moved into operative position, inwhich it sets in motion the leoni-controlling mechanism.' c* rln the preferred embodiment of my invention the lock forV the retainer is adapted to be released both when the weft is substantially exhausted and whenever a float occurs, although it is not essentialthat the locking device'be arranged so as to be operative when either or both of these conditions arise.

.lntle drawings, Figure 1 is a top plan view of one shuttle-box of a loom and part of the breast-beam, said view also showing part of the opposite shuttle-box. Fig. 2 is a top plan view of a shuttle embodying my inveniien. Fig. 3 ya side view thereof. Fig. 4 is a section von n n enlarged scale, von the line a; at,

Fig. Fig. 5 is n, section on substantially l the limx 1; Fig. 2. Fig., (i is a detail view cf the emtrellvr. Fig. 7 a detail of thelockmg :marbmrismyl'or theretamer. Fig. S is a right-hand end view of Fig. 7, and Fig. 9 is a section through the spindlevand bobbin atthe buttof the latter.

` ln the drawings, 3 designates the shuttlebox of a loom 4, the lay); 5, the shuttle, and

6 the shipper-lever. These parts, with the exception of the shuttle, may be of any suitable or usuall construction and form no part of my present invention.

The shuttle is provided with a controller 7, herein shown as a member pivoted to the shuttle in the side thereof and adapted -to be moved by a suitable spring or equivalent' means 8 from its inoperative position, such as snown in Fig. 2, wherein 1t lies within the walls of the shuttle, to its operative position,

(shown in dotted lines, Fig. 2,)'in which the outer end thereof projects beyond-the shuttle and is in position to engage a suitable loom-controlling mechanism as the shuttle enters the box. a l

The controller is normally held in its inoperative position by means of a suitable retainer 9, herein 'shown as a member pivoted to the shuttle in some suitable way, as at 10. The controlleris made with the hooked pori-1 tion 1.1, which embraces the endof the retainer 9 ,-and said retainer is sh aped to present a head 12 at its extremity and a neck .portion 13. The head 12 is shaped to present oppositely-extending ,lips 14 and 15, thelip 14 being thinner than the lip 15, as best seen in- Fig. 7. f .l

Under normal working conditionsk the head of the retainer is so positioned inthe hooked end 11v of the controller that the thinner lip 14 stands beneath the end of the retainer, while the thicker lip 15 projects through the throat 16 ofthe controller and by its engagement with the walls ofthe controller forming lthe sides of said throat prevents said controller from turning movement Kabout its pivot 17. If, how.ever,'the retainer 9 is depressed, so as to carry the lip 11253 entirely below the level of the eontrollerthe latter is caused to swing about is pivot by the' spring 8, and thus throw the free Iend 18 thereof into operative position, the-neck 13 of the retainer at this time loccupying the recess 19 in the controller. 'T1211 prevent the 'retainer from being depressed, thereby to release the controller, except when 'the abnormal conditions arise, l

roo

retainer and as normally engaging theunpper released and th side of the hook 11 of the controller, as seen 2i, l ter isthrown into its inoperative position out of engagement with the controller. For actuating the locking-pawl to release the re- V tainer I have herein shown a releasing-lever 22, which is pivoted either to the shuttle or to the retainer in any suitable way'. Prefer- 1 ably, however,l it would `be pivoted on the pivot 10 of the retainer 9, and the retainer 9 will be slotted to receive the releasing-lever.

W'hen my invention is to be float detector, I propose to locate the retainer and the releasing-lever 22 above the top of the shuttle, (shown best in Figs. 3 and 4,) lso that whenever afloat occurs the misplacedwarps will by their engagement with the releasing-lever 22 depress 'the latter, thereby releasing the retainer and permitting the latter to be depressed by said misplaced warps until the controller V7 is released. In this case the releasing-levers 22 and retainer 29 constitute iioat detecting members, Where the invention, however, is used for setting in motion certain loom-controlling mechanism or weft-replenishing mechanism when the weft in the shuttle has been substantially orcompletely exhausted, it isnot necessary to place thereleasing-lever and retainer above the side of the shuttle.

lFor operating the releasing-lever when the weft is substantially exhausted I have shown the outer end 23 of said lever as resting on the end 240i a weft-controlled member 25, which is pivoted to the shuttle in any suitable way, asat 260. This member 25 has an arm 26 extending therefrom and -provided with a yprojection 27, which engages a finger 28, carried by the shuttle-spindle` and adapted to occupy a recess 29 in the bobbin 30. f The weft on'the 'bobbin is wound around outside' the ringer 28 andholds said finger within the recess, and said finger, acting against the projection 27 and the arm 26,-holds the member 25 in its inoperative position. The end 24 of said member 25 is providedwith a cam-surface 31,v and said member is acted upon by a suitable spring 32, which tendsnormally to throw said member outwardly. Whenever the weft is exhausted, or substantially exhausted, from the bobbin, the finger 28"is e member 25 thrown outwardly by the spring 32. During this movement the cam surface 31 acts against .the right-hand end of the releasing-lever 22, thereby turning said .lever about its pivot.

The .initial turning-movement of the releasing-lever actuatcs the pawl 20 and releases the retainer 9, and the continued used vas a l movement of said releasing-lever 22 brings the flanges 33 thereon against the top of the retainer 9 and depresses the lattersuiiicientl)v to release, the controller.

wit, whenever the weft is exhausted and -whenever a iioat occurs. f

believe I amthe first to provide a shuttle with a controller 4which is constructed to be released when either ,one of two different conditions arises, and therefore I desire to claim this feature broadly. It is not essential,v

i however, to the invention that the controller be arranged to be released when both of these conditions arise, as the invention could be embodied in a shuttle adapted to detect floats only or a shuttle adapted to operate the loom-controlling mechanism only when the weft is exhausted.

Thecontroller is adapted to coperate with any suitable loom-controlling mechanism, and for the lsake Aoi illustration I have herein shown such mechanism as comprising atrip 40 on the lay, which is connected by a rod 41 with a bunter 42, also piv'otedv to the lay. The bunter is normally held "out 'of line with the shipper-lever 6 by means of a suitable spring 43; but A.whenever leased it engages the `trip and 'turns the latter' .so as to throw the. bunter into line with the the. controller 'is reshipper, and `when the laybeatsup atthe 'next turn said bunter'throws the shipper out of the -locking-not'ch, thereby stopping the loom. Any other Icom-controlling mechanism maybe employed, however, without de- I parting from the invention. Having described lmy invention, what' I claim as new, and desire rto secure by Letters is. l i

1. A shuttle, a controller carried thereby, means 'to holdthe controller normally inl inoperative position, and'means to release the l controller whenever the weftin the shuttle is substantially'exhausted, or whenever a float occurs in the warp-threads.

2. A shuttle, a controller carried thereby, and means actuated either by the exhaustion of the iilling or the existence of a float. to actuate the controller.

3. A shuttle, a controller carried thereby, a lock to hold said lcontroller in inoperative position, and means to actuate said retainer rooA IIO

7. Ina shuttle, a controller,` a retainer to ,hold said controller normally in inoperative `from movement, and means set in motion either by the existence of a float or Vthe eX- haustion of the weft to actuate the paWl thereby to release the retainer.

9. In a shuttle, a controller, a retainer to hold said controller normally in inoperative positlon,

and a releasing-lever to actuate said paWl.

10. In a shuttle, a controllerhaving a hook-shaped end and a pivoted retainer prof vided With a head to normally ,occupy the throat of said..hookshaped end.

11. In a shuttle, a controller having. a hook-shaped end7 a pivoted retainer provided With a head normally occupyingr the throat of said hook-shaped end, a lockingpaWl .carried'by the retainer and adapted to engage, the controller,l and a releasinglever for actuating said pawl.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
